However, she must have had a bit of a change of heart following Katie's latest attack, which saw her write on Twitter: "Jesus. John Lewis has a sale on jumpsuits 'one size too small'. Has anyone told Sam Bailey?"

If rumours are to be believed, Katie is currently gearing up to enter the 'Celebrity Big Brother' house on Friday, as she is reported to be one of the housemates forming the "most controversial line-up ever".

Meanwhile, Sam's lost out on having the last number one of 2013, as her single 'Skyscraper' was pushed down to number two by Pharrell with 'Happy'.

There was no hard feelings though, as she tweeted: "Well done @Pharrell for the number 1 spot xx love it xxx."
